CAR-TIPPLE.

Specification of Letters Patent.

Patented Apr. 8, 1919.

Application filed June 21, 1917. Serial Ila-176,126.

To all whom it may concern Be it known that I, ALEXANDER a citizen of the United States, residing in This invention relates to improvements in' car tipples more especially of the type designed to receive mine cars loaded with coal, ore or other material, and to overturn them to discharge their contents. contemplates a car tipple mounted to rotate on a horizontal axis w' rails in its bottom to support a car, the gene al tipple structure being made in accordanc with well known principles, and this inve tion' relates more particularly tothe mean for rotating -the tipple and for restoring it to its normal position. A

An apparatus embodyin the principles of the invention comprises in general terms the rotating structure designed to receive a car and preferably made in the general form of an open-ended, horizontal cylinder, around which there is wound a rope or cable with the two ends of the latter connected to the piston rods of a cylinder or cylinders by means of which a pull may be imparted to the rope or cable from either end to rotate the tipple cylinder.

An apparatus embodying the principles of the invention is illustrated in the accompanying drawings in, which:

Figure 1 is a view of the complete tipple and operating mechanism in end elevation.

Fig. 2 is a similar view showing a modified form of the operating mechanism.

Fig. 3 is a radial section through one of the valves of the apparatus.

Fig. 4 is a radial section through the other valve of the apparatus.

-As shown in said drawings in Figs. 1, 3 and 4, the car tipple is made in the general form of a large horizontal cylindric structure, 10, resting on wheels, 11, and adapted to rotate about a substantially horizontal axis, the framing in the lower part of the cylinder supporting a pair of rails, '12, adapted to receive a loaded car which is overturned by the rotation of the cylinder to empty its load. This part of the apparatus is made in accordance with well known principles and its particular design or construction is not involved in this invention The invention 1 except that the cylinder is made in such form as to provide at some place in its length a circular section in the form of a' drum about which is wound a rope or cable, 24.

In any convenient location adjacent to that side of the cylinderlO toward which its upper part rotates in the dumping operation is located a cylinder, 30, in which is a movable piston, 31, with a piston rod, 32,. attached to one end of the cable 24; the latter passing over a sheave, 33. The other end of the cable is led" around a similar sheave, 40, and attached in the same manner to the end of a piston rod connected to the piston in.a cylinder, 44; and the two cylinders are connected by suitable pipingto a source of fluid pressure, preferably pneumatic, here shown as an air pressure tank, 50, although if desired the apparatus may be worked equally efl'ectively with steam, and in such case the air tank 50 would be replaced by a a steam boiler.

From the pressure tank or storage tank 50 a pipe, 55, is connected to one of the ports of a 4-way valve, 56, and the opposite port,

57 of this valve opens into the atmosphere.

-One of the intermediate ports is connected through a pipe, 60, to the pressure side of the cylinder 30, and the remaining port is connected through a pipe,'63, to the pressure side of the cylinder 44. In addition there is interposed in the pipe 63, between the valve 56 and the cylinder 44 a 3-way valve, 70, one of the'ports of which is open to the atmosphere.

In the operation of the device, after a loaded car; or a trip of two or more cars,

has entered the tipple, the-4-way valve 56 is adjusted to admit air or steam into the cylinder 30 and to permit it to escape from the cylinder 44 whereby the pull on the rope or cable 24 imparted by the cylinder 30 acts to rotate the, tipple and overturn the cars; this rotating operation being permitted by allowing the air or steam to escape from the cylinder 44 through the pipe 63 and the outlets of the two valves 56 and- 70, while at the same time the cable is kept tight and the rotation is checked and controlled by adjusting the valve 70 to restrict the outlet from the pipe 63 to any desired extent and retard the escape of air from the cylinder 44, which latter acts as a brake in the overturning operation. When it is desired to return the cars to their upright position the valve 56 is adjusted into its opposite position, as shown in Fig. 3, to permit the escape of pressure from the cylinder 30 and to utilize whatever pressure may remain in the cylinder 4% after serving to cushion the movement of the tipple; such additional air or steam as maybe necessary being supplied to the cylinder 44 from the pressure tank 50 to return the tipple to its normal position. .l-his additional air is admitted to the cyllnder through the pipes 55 and 63 and the valve 70, which latter may be adj usted to permit a straight passage of air through it, either restricted or unrestricted, or, if desirable, it may be adjusted to restrict the passage of air through it and also to permit some of the air to escape through its third port into the atmosphere, as shown in Fig. 4, so as to avoid too great pressure in the cylinder 44 and a too violent return of the tipple to its original position, this adjustment of the valve being called splitting the air and allowing part of it to enter the cylinder and part of it to escape.

If the valve 70 is adjusted into such a pos1t1on as to permit an unobstructed discharge of fluid-straight through it and no escapethrough it's outlet port it is evident that it vwill have no efl'ect whatever in the operation of the mechanism, and this-Valve mlght be omltted from the mechanism without seriously impairing the efiectiveness of its operation; but .the addition of this valve is believed to be desirable as it permits of restricting the outlet from the cylinder 44 independently of the position of the 4-way valve, and it also permits of restricting the admission of fluid to the cylinder 44 and oi splitting the air and allowin some of i to escape, likewise independent y of the po-- sition of the 4-way valve.

' The rotation of the tipple structure or cylinder 10 in either direction is limited by a projecting stop or lug, 75, which engages against oneof two posts, 7 Sand 7 7,, accordmgto the dlrectlon of rotation; the opera- .tive movement of-rthe tipple being counter clockwise, as viewed in Fig. 1, to overturn the 'car or cars and discharge their load down into a chute, 80, below the tipple, and the return movement being in the opposite direction.

In Fig. 2 is shown a form of the appa ratus substantially similar to that above described, with a rotary tipple. structure, 90, and a rope or cable, 91, wound about itito impart movement thereto, but the ends of the cable instead of connecting to two pneumatic or hydraulic cylinders, are-connected to the free ends of two piston rods which are joined to a single piston, 98, in a double-acting cylinder, 99. The two ends of the cylinder are connected through a 4-way valve, 100, and a 3-way valve, 101, similar in all respects to those above described, with a storage tank or steam boiler, 102, and the operation of the-mechanism is exactly the same as that above described except that the operating fluid is admitted to one end of the cylinder 99 in the overturning movement and exhausted from the other end and to restore the tipple the piston is driven in the opposite direction by reversing the direction of admission and exhaust, as will be readily understood.

A pulley 110, supporting a weight 112, is hung on the rope to take up slack.

I claim as my invention:

An operating mechanism for rotary tip- I ALEXANDER H; woon.
